WINDOW-LOCK AND ALARM.

Specificationof Letters Patent.

Patented Mar. 18,1919.

To all whom it may concern:

Be it known that I, Isroonn Fran, citizen of the Republic of Russia, and a resident of New York, have invented certain new and useful Improvements in Window-Locks and Alarms, of which the following is a specification. I

Thepresent invention relates to improve ments in window locks and alarms. The object of the invention is to'provide a simple, convenient, economical and efficient devicefor locking windows either in closed or partially closed position and for giving an alarm if any attempt'is made to open the window. The locking and signaling devices are so associated that many of the parts are common to both and this simplifies the construction. The locking-device is set and the alarm is initiated upon even a very slight movement of the window sash. The alarm is not only started by vertical movement of either sash of a window but also when a sash is pressed inwardly and this may serve to defeat any attempt to tamper with the window at its inception.

The alarm proper may be mechanically or electrically operated and in the drawings I have shown both arrangements. Other features will be set forth in the detailed description hereinafter.

In the drawings plication,

Figure 1 is a cross sectional view of a window showing my invention applied thereto,

Fig. 2 is a front elevation thereof,

Fig. 3 is a detail of the parts which initiate the alarm,

Fig. 4 is a view similar to Fig. 1 but looking from the opposite direction,

Fig. 5 is a view similar to Fig. 4. but showing the throw off device set to prevent the operation of the locking and alarm deforming part of this apvices,

Fig. 6 is a sectional view taken on the line 66 of Fig. 5, I 9

Fig. 7 is'a side elevation of a modification in which the signal is electrically operated,

Fig. 8, is a front elevation thereof,

Fig. 9 is a view showing the electric circuit.

The device is preferably mounted on a base or frame which is adapted to be attacheclto oneof the window sashes prefercity and State of ably the lower one. The base shown herein comprises the angular plate 1 which is adapted to be secured by screws 2 to the face and top of the rail 3 of the lower sash near one side of the sash. There is a casing 4 for inclosing the parts at one side, with a hinged cover 5, closed by a spring 6 for inclosing the parts at the front. standard 7 rising from the base 1 and it has cars at the top through which a pin or shaft 9 extends. The locking member is arranged to both rock and move laterally on this pin.

The locking member is shown provided with an oblong aperture 10 through which the pin 9 extends, with the longer axis of the opening extending substantially horizontally when the locking member is positioned for operation. This locking member consists of the plate 11 having the aperture 10 and' of a plate 12 secured thereto in suchrelation that the parts may be adjusted to alter their length. These plates are roughened or provided with teeth 13 where they. overlap and they are clamped together by a bolt 14 which passes through the slotted aperture 15. By loosening the bolt 14L the plates 11, 12 may be adjusted to alter their combined length or to adjust the plate 12 toward or from the pivotal pin 9. The plate 12 has a rocker or shoe 16 at its outer end which is adapted to engage the side member 17 of the upper sash. This rocker is so designed that the upper part 18 of. its rocking surface is farther from the pivotal pin 9 and the lower part 19 thereof isnearer the pin. It will be There is a obvious that when the rocker or cam memher is set as shown in Fig. 1, any upward movement of the lower sash or any downward movement of the upper sash will tend to rock the rocker or eccentric on its pin, the free or camend of the rocker moving downpivot 9' and'this alone will-initiate the oper- 'wardly. As the rocker member swings ation of the alarm device, as will be apparent from the description hereinafter.

The rocker may be held out of operation when it is desired to wash the window or whenever it is desired to throw ofi the alarm and lock. There is a sliding plate 20 which is secured to the frame by a screw 21, which passes through the slot 22- and into the frame which connection permits the plate 20 to slide up and down. The plate 20 has a lateral projection 23 arranged under the rocker member and when the plate 20 is in its upper position this projection is adapted to support the rocker member and prevent its operation by the sashes. There is a pawl 24 hinged at 25 to the plate 20 and its in- I turned end 26 is adapted to engage in a recess '27 in the frame for the purpose of holding the plate 20 and the rocker member in raised position when the throw off is in operation; and the projection 26 lies below the end of the frame when the parts are down. The hinged finger piece 28 may be used to raise and lower the pawl 24 and the parts moved by it. In Fig. 4 I have shown the throw off device down, with the rocker operative, and in Fig. 5 I have shown the throw off device positioned to hold up the rocker.

The signal device shown in Figs. 1 to 6 includes a spring bell. These are well known devices which may be purchased in the market. They comprise a bell proper which is connected with a main spring for operating the striker the main spring being wound up by turning the bell. It is unnecessary to an undestanding of my invention to show every detail of the bell construction especially so asany other form of bell or signal device 'may be used in the combination.

The 'bell 29 shown herein is one of the type-referred to and it is mounted on the.

frame. Pressure on the button 30 is adapted to initiate the operation of the bell. The bell base has upstanding walls 31 through which a rod 32 passes, the latter being adapted to rock in these plates. The rod is bent back upon itself to provide a portion 33 which is off the axial line of the part 32 and the part 33 has a loop 34 which is in' line with the operating button 30 of the bell and with which button it is adapted to engage for the purpose of initiating the operation of the bell. The rod has a portion 35 which is also offset from the axial line and thisportion rests against the plate 11 and holds the rocker over so that the pin 9 lies in the slot 10 in the'relation shown in Fig. 4.

The spring (not shown) which presses out the button 30 holds the rod 32 and other parts in the positions shown in Fig. 4 until the rocker is forced laterally on the pin 9.

I11 setting up the device the frame is applied to the sash rail at onesi-de of the'sash.

and if the rocker member should not rest in the proper position againstv the side of the upper sash, then the bolt 14 is loosened and the plat-e12 is moved in or out to secure the proper adjustment and the bolt is then tightened. This adjustment makes it possible to adapt a standard article to various sashes, without necessarily changing the sashes themselves. If the plate 20 is in its lower position the rocker member will rest against the side rail 17 of the upper sash and the button 30 will hold the rod member 32 in the position shown in Fig. 4 and this will hold the rocker as shown. If the upper sash is then moved downwardly, even if only a slight extent, or if the lower sash is raised, then the rocker member will be turned on its pivot 9. As the rocker moves downwardly it is forced laterally .on the pin 9 because the contact of the eccentric surface changes to a point farther from the fulcrum 9. When the opposite edge of the slot 10 strikes the pin 9 the rocker can not move laterally any farther and therefore it cannot move downwardly any farther and the sashes are thus locked. The rocker in its lateral movement on the pinr9 actuates the rod portion 35 so that the rod as a whole is rocked to press the portion 34 against the button 30., This will start the bell ringing and the alarm will indicate that an atttempt is being made to open the window. 7

If the upper sash is pressed inwardly, even before any attempt is made to raise or lower one of the sashes, the rocker member will be forced laterally on the pin 9 and this will initiate the alarm. The rocker, therefore, is adapted to initiate the alarm even if pressure is brought to bear. on the window for the purpose of cutting out a portion of the glass. 7

To throw off the lock and alarm it is only necessary to openthe cover 5, grasp the'finger piece 28 and to pull outwardly and up,- wardly until the end 26 of the pawl 24 engages in the notch 27 when the device will be rendered inoperative as shown in Fig. 5. The window may then be opened and no alarm will be sounded. To set the device again the pawl 24 is moved down to its lower position.

In Figs. 7 and 8 I have shown an electrically operated signal. In thisconstructi on there is a lever pivoted at 36 and having one arm 37 engaging the rocker. The other arm, 38 is pressed outwardly by a spring 39 to hold vthe rocker over on its pin 9 andto hold the lever, out of contact with the contact member 40. If the rocker is moved overon its pin 9 in the manner set forthin connection with the previous construction, the lever arm 37 will 'be forced outwardly and the arm 38 will be moved into contact with the point 40. This will close a circuit including the wire. 41, the wire 42 connected with the com 130 tact member 40 and the battery A3 and bell This will cause the bell to ring. The throw off device is operated in the same manner as in the previous construction.

From the above it will be apparent that I have provided a very simple and positive window lock together with a simple alarm device, both of which are operative upon very slight movement of the sashes.

It will be apparent that the device will be operative whether the window is closed or partly open.
